Bently Nevada 21000 Proximity Probe Housing Assembly

Exact configured model: 21000-16-10-00-120-03-02

Official product identity

The 21000 is an all-metal assembly for externally mounting a proximity probe. This configuration combines the aluminum housing and 304 stainless steel sleeve with a 3300 XL 8 mm reverse-mount probe and 1.0 m probe cable.

Configured geometry

No standoff adapter is supplied. Probe penetration is 12.0 in (304.8 mm). The housing reference dimensions are A 83.3 mm, B 161.6 mm and E 26.7 mm.

Connection package

Option 03 supplies one 3/4-14 NPT plug, one 3/4-14 to 1/2-14 NPT reducer and one cable seal grip with three grommet ranges. The mounting thread is 3/4-14 NPT.

Installation focus

The probe lead must be longer than the sleeve. Verify machine-case clearance, target gap and cable routing before installation. The official datasheet requires added sleeve support when the combined standoff and penetration length exceeds 12 in.

Procurement check

Match every segment of 21000-16-10-00-120-03-02. The probe type, cable length, standoff, penetration, fitting package and mounting thread jointly define the supplied assembly and are not interchangeable by model similarity alone.

Construction

All-metal housing

The 21000 assembly uses an aluminum body with a 304 stainless steel probe sleeve. A threaded dome cover closes the housing while O-rings and a thread seal support the mechanical enclosure.

Probe assembly

The configured A:16 option incorporates a 3300 XL 8 mm reverse-mount proximity probe with connector. The B:10 option supplies a 1.0 m (39 in) probe cable.

Conduit and cable entry

Two threaded housing ports accept the selected connection hardware. Option E:03 includes a 3/4-14 NPT plug, a 3/4-14 to 1/2-14 NPT reducer and a cable seal grip with grommets for 1/8–3/16 in, 1/4–5/16 in and 5/16–3/8 in cable ranges.

Configured mounting interface

The F:02 selection provides a 3/4-14 NPT mounting thread. The C:00 selection means the assembly has no standoff adapter.

Installation

External mounting

Install the housing externally on the machine at the measurement point and use the specified 3/4-14 NPT mounting interface. Confirm thread condition, probe orientation and machine-case clearance before tightening.

Penetration and support

Option D:120 defines 12.0 in (304.8 mm) probe penetration with no standoff adapter. The official datasheet requires additional sleeve support when the combined C + D length is greater than 12 in; verify support and resonance risk for the actual installation.

Cable and probe clearance

The probe lead must be longer than the sleeve. Route the 1.0 m probe cable without sharp bends or strain, preserve connector access, and confirm that metal around the probe tip will not cause side-view or rear-view effects.

Final setup

Set the working gap according to the applicable 3300 XL 8 mm Proximity Transducer System instructions. Confirm mechanical security, cable sealing and correct target geometry before commissioning.

Selection Guide

21000

Aluminum 21000 Series proximity probe housing assembly for external mounting.

16 | Probe

3300 XL 8 mm reverse-mount probe with connector.

10 | Cable

1.0 m (39 in) probe cable.

00 | Standoff

No standoff adapter.

120 | Penetration

12.0 in (304.8 mm) probe penetration, ordered in 0.1 in increments.

03 | Fittings

3/4-14 NPT plug, 3/4-14 to 1/2-14 NPT reducer, and cable seal grip with three grommet ranges.

02 | Mounting thread

3/4-14 NPT mounting thread. Every suffix must match the purchase order and nameplate evidence.

Environment

Temperature range

For the supplied 3300 XL 8 mm probe, the official operating and storage range is -51 to +177 °C (-60 to +351 °F). The datasheet cautions that exposure below -34 °C (-30 °F) may cause premature failure of probe pressure seals.

Materials and mass

The aluminum body and 304 stainless steel sleeve form the all-metal assembly. Typical mass is 1.1 kg (2.4 lb) without fittings; the configured option 03 hardware adds to the installed mass.

Compliance

The official datasheet lists compliance with European Community RoHS Directive 2011/65/EU.

Hazardous-area distinction

This exact model begins with 21000, not CA21000. The datasheet reserves CSA explosion-proof ratings for CA housings with specific fitting options; option E:03 is not among the CA explosion-proof combinations. Do not represent this exact configuration as a CA-rated explosion-proof assembly.

FAQ

Q1. How do I verify that a quotation is for the exact complete model?

Require the supplier to show 21000-16-10-00-120-03-02 on the product label, packing label and quotation. Check each option: 3300 XL 8 mm probe, 1.0 m cable, no standoff, 12.0 in penetration, fitting package 03 and 3/4-14 NPT mounting thread.

Q2. How can I distinguish New, Used and Refurbished condition?

Ask for current, high-resolution photographs of the aluminum housing, dome threads, 304 stainless steel sleeve, probe tip, connector, 1.0 m lead, fittings and labels. A new unit should have consistent unused surfaces and no installation marks, field-wiring residue, thread wear or replaced labels.

Q3. How can I check whether the supplier is legitimate and reliable?

Verify the supplier company registration, business address, bank-account beneficiary and traceable contact details. Request a written quotation that identifies the complete model and condition, then cross-check the supplied option breakdown against Bently Nevada datasheet 141600 Rev. AC before payment.

Q4. Which specifications must an engineer confirm before purchase?

Confirm the 3300 XL 8 mm probe type, 1.0 m cable length, 12.0 in probe penetration, absence of a standoff adapter, 3/4-14 NPT mounting thread, fitting option 03, target clearance, cable routing and the -51 to +177 °C probe temperature range. Also review the sleeve-support threshold for the installation.

Q5. What physical evidence should be requested before payment?

Request dated photos or video showing the full assembly, complete model label, probe and connector, cable length marking, sleeve and dome, option 03 plug/reducer/seal grip, and 3/4-14 NPT mounting interface. Ask for packing evidence that links the photographed item to the quotation.

Q6. Can a similar 21000 suffix or another housing replace this model?

Not automatically. Changing 16, 10, 00, 120, 03 or 02 changes the probe, cable, standoff, penetration, fittings or mounting thread. A CA21000, 24701, 164818 or another 21000 configuration can also differ in material, dimensions or approvals. Replacement requires an engineering review of every option and installation dimension.
